When shooting at low temperature, the camera's lithium battery may fail in a low temperature environment for a long time, so try to ensure the body temperature. So be sure to pay extra attention to camera insulation. Because of the cold temperatures outside, it's best to hide the camera under your clothes until you need it. If you do not do this, the camera suddenly from the low temperature environment to the indoor high temperature environment, the lens and CMOS in the fuselage may appear condensation problems. It is recommended that the camera be exposed for no more than half an hour in the wild.

In general, camera batteries are fine for shooting at minus 10 degrees Celsius; Most mid - to high-end cameras are fine shooting at minus 20 degrees Celsius; But shooting at minus 30 degrees Celsius is a matter of luck. Because in low temperature conditions, lithium battery power is very easy to dry up, this time the battery storage is only about 70% of the normal temperature. So when shooting outside must prepare a few more lithium batteries, but also remember to turn off the power when not shooting, in order to save power. Similarly, if you have an external battery case as a backup power source, you can also place the battery case in your clothes to power the camera through a wire, or you can sew or buy a battery insulation device.
